PROCESS OF PRODUCING COLORED PICTURES N POTTERY AND PORCELAIN.

E:PECJIP ICJATION forming part; of Letters Patent No. 297,608, dated April 2 9, 1884.

Application filed November 23, 1883. (No specimens.)

To all whom it may concern:

Be it known that we, AUGUsr KiiRTH, of Leipsie, and ROBERT BEYERMANN,.,0f Gross Breitenbach, Germany, citizens of Germany, have invented a new and useful Improvement in the Process of Producing Colored Pictures on Pottery and Porcelain, of which the following is a specification.

Instead of painting the desired picture upon pottery or porcelain, the picture printed in colors upon paper is applied to the surface, after which the paper isremoved and the colors remaining upon the article burned into the same in the well-known manner. By this process the different colors forming the picture are very often more or less mixed or run into each other, and the desired picture loses its distinctnessand sharp outlines.

To produce pictures upon pottery and porcelain perfectly sharp and clear is the nature of our invention; and it consists in the use of the chromo-lithographic process for this purpose. We print the different colors forming the picture desired to be reproduced upon the pottery or porcelain article separately, and apply the same, one afterv the other, to the article, and burn each color into the same before a different color is applied, until the whole design or picture is completed.

According to the nature 'of the design or of the nature of the colors themselves, two or more colors may sometimes be in this manner 7 transferred tothe surface of the article and burned into the same at the same time.-

By this process we are able to reproduce any design or colored picture-upon pottery or lithographic process for the reproduction of colored pictures on pottery and porcelain, in the manner and for the purpose substantially as described.
